Abstract: A system for ink jet printing of messages on articles being fed forward one after another in a predetermined path. A terminal includes a keyboard for entering message data representative of the messages. A controller interconnected with the terminal processes the message data received from the terminal and stores the message data for the messages. The controller has an output port for providing serial output data in a bit map format representative of the messages. A plurality of ink jet printheads are serially connected and positioned adjacent the path of the articles to print the messages on the articles in response to the serial output data. A single cable connects the output port of the controller to the first printhead for providing the output data to the first printhead. A separate cable interconnects each printhead to its next succeeding printhead for serially providing the data to the remaining printheads so that the printheads are connected in a daisy chain configuration.

Abstract: Central processing unit, responsive to the commands and print data signals, selectively stores the reference pattern signals from a pattern memory into a page memory. The central processing unit provides the first page pattern signal stored in the page memory to the laser printer engine for use in printing the first page while simultaneously providing the second page pattern signals from the pattern memory to the page memory to build the second page in the page memory. After the first page pattern signals have been provided to a laser printer engine, the central processing unit provides the second page pattern signals stored in the page memory to the laser printer engine for printing while simultaneously providing the subsequent page pattern signals from the pattern memory to the first page memory to build the subsequent page in the page memory. A bus interconnects the computer and the central processing unit, the pattern memory and the page memory and the page memory and the laser printer engine.

Abstract: An electronic device for managing at least two bingo cards. The device has stored standard card configurations which correspond to physical cards which have been selected by a player. Also stored are standard winning patterns. The processor compares "called" numbers with card configurations which correspond to the physical cards being played by the user. The device alerts the player when a winning card occurs. When "padded" paper cards are used, the device generates each succeeding game board.

Abstract: Line security apparatus for a direct-wire alarm system utilizes a transmitter at the remote premises to impose on the direct current a small amplitude carrier frequency which is on/off modulated by a clocked, continuous progression of pseudo-random digital bits. A receiver, tuned for the carrier frequency, is utilized at the monitoring station to recover the progression of digital bits, if received at the monitoring station. A microprocessor at the monitoring station produces an identical and initially synchronous sequence of digital bits, compares the produced sequence to the progression of bits received, and effects a temporary alarm signal indicating that the line security is disrupted if the bits do not correspond. Because the lack of correspondence may be due to deviations of the transmitter and microprocessor clocks, the microprocessor seeks correspondence by shifting the produced sequence and, if successful, continues the comparison as shifted.
